need solution to code

[mccluregamer4472]

this is what i have so far

class batch:
    def _init_(self, batch_number, components_in_batch):
        self.batch_number = batch_number
        self.components_in_batch = components_in_batch

    def _init_(self, type, size):
        self.type = type
        self.size = size

    components_list = ["1 = Winglet Strut", "2 = Door Handle", "3 = Rudder Pin"]
    print(components_list)
def chosen_component():
    print()
def chosen_size():
    print()

print("please select an option")#
print("1 = create a batch")
print("0 = exit")
while True:
    choice = input("> ")
    if choice == '1':
        print("welcome to the program")
        #batch_number = batch_number + 1
        #print("batch number is " + (currentDT.strftime("%d%m%y") + str(batch_number).zfill(4))
        break
    elif choice == '0':
        print("you have selected to exit program")
        break
    else:
        print("invalid choice")
    print()

while True:
    print("what component?")
    component = input("> ")
    if component == '1':
        print("you have selected Winglet Strut.")
        chosen_component == 'component'
        break
    elif component == '2':
        print("you have selected Door Handle")
        chosen_component == 'component'
        break
    elif component == '3':
        print("you have selected Rudder Pin")
        chosen_component == 'component'
        break
    else:
        print("invalid choice")


sizes_list = ["1 = A320 Series", "2 = A380 Series"]
print(sizes_list)
while True:
    print("Please select the size of the of the component")
    size = input("> ")
    if size == '1':
        print("you have selected the A320 Series")
        chosen_size == 'size'
        break

        break
    else:
        print("invalid choice")


while True:
    if chosen_component == 1 and chosen_size == 1:
        print("you have selected Winglet Strut A320 Series")
        break
    elif chosen_component == 1 and chosen_size == 2:
        print("you have selected Winglet Strut A380 Series")
        break
    elif chosen_component == 2 and chosen_size == 1:
        print("you have selected Door Handle A320 Series")
        break
    elif chosen_component == 2 and chosen_size == 2:
        print("you have selected Door Handle A380 Series")
        break
    elif chosen_component == 3 and chosen_size == 1:
        print("you have selected Rudder Pin A320 Series")
        break

        break
    else:
        print("invalid process")
    break

i need to create the batch number still, ive tried a few solutions but it hasnt worked and i also need the final while loop to work as it needs to read from the 2 previous outputs to get its information
